This read-only object reports the measured frequency offset in Hz (100 Hz resolution) of the carrier being demodulated, ranging from -200,000 to +200,000 Hz. Functionally identical to cdd564RxFreqOffset, a persistent nonzero offset here across multiple different carriers points to this unit's own reference needing adjustment, while an offset specific to one particular remote transmitter's carrier points instead to that far end's own LO accuracy or Doppler effects. A steady positive offset appearing consistently on every carrier this unit receives, regardless of which remote it's talking to, would prompt an admin to check this unit's own reference frequency configuration rather than suspecting each individual far-end transmitter.
